Description:
If you open a LibreOffice document and choose the Alegreya typeface, on 
accessing Character>Feature, you may choose between two Fraction styles: 
diagonal (frac=1) or nut (frac=2). If you press Ok, one of them (the chosen 
one) will be applied. Whatever other option you select and press Ok, the 
selected Fraction style will be applied. You can not select frac=0, or no 
fraction style. I guess there should also be a checkbox next to Fraction style. 
It works the same in Writer, Calc and Impress, too.
There is a workaround: after applying the desired features edit the text in the 
Font: field and delete frac=... however it is not so elegant, there should be a 
check box next to the stubbornly self-applying feature, as I said above.

Steps to Reproduce:
1.Open a new document.
2. Go to Character, select the Alegreya typeface.
3. Choose a feature (anything) and one of the Fraction styles will be applied.
4. Press OK.

Actual Results:
One of the Fraction styles will be applied. You can not select no fraction 
style.

Expected Results:
Besides the offered fraction styles it should be possible to chose 'None'.

On pc Debian x86-64 with master sources updated today, I could reproduce
this.

But there are also these:
- frac option has some impact visually but frac=1 and frac=2 are very similar 
effects, quite difficult to distinguish them.
- also when closing and reopening the dialog, ":frac=1"/":frac=2" disappears.
I don't know if it's expected.
However, if I use both of them at different locations, I can see their 
associated font indicate "Alegray" with frac option.

Xisco/Heiko: any thoughts here?

I don't see any difference ;-)

The dropdown has a blank entry when you open it the first time (though
not selectable). We should introduce a "No Fraction" option.

IIUC, the nut fraction should be a horizontal line between numerator and
factor.

Title:
  LibreOffice 6.4 OpenType Features unusable

Status in LibreOffice:
  Fix Released
Status in libreoffice package in Ubuntu:
  New

Bug description:
  When using OpenType features (Format - Character - Feature) from a
  capable font like EB Garamond 12, LibreOffice automatically enables a
  fractional style, which essentially makes all numerics unusable, and
  there's no obvious way to disable this in the GUI once you've opened
  the Features dialog.

  There are two workaround, as all OpenType features get disabled when
  selecting another font, and back again.

  And, of course, one can remove :frac=1 manually from the font name
  field.

  This has however been fixed in LibreOffice 7.0 onward, but somehow
  wasn't cherrypicked into 6.4.x, even though the change seems trivial:

  
https://github.com/LibreOffice/core/commit/d28c9d56df8a2629321bda116a6d2dcfa587d160

  Please consider including this cherrypick in a future package for
  Ubuntu Focal.

  The patch won't apply directly due to a filename typo getting
  corrected, which needs to be uncorrected in the patch:

  vcl/source/font/OpenTypeFeatureDefinitionList.cxx
  vcl/source/font/OpenTypeFeatureDefinitonList.cxx
